INPUT/OUTPUT SIGNAL TABLE

SYSTEM DESCRIPTION

• CVT detects the vehicle driving status from switches, sensors and signals, and controls the vehicle so that

the optimum shift position and shift timing may always be achieved. It also controls the vehicle to reduce

shift and lockup shock, etc. 

• Receives input signals from switches and sensors. 

• Sends the output signal necessary for operation of solenoid valves, and evaluates the line pressure, shift

timing, lockup operation, engine brake performance, etc. 

• If a malfunction occurs on the electric system, activate the fail-safe mode only to drive the vehicle.

CVT CONTROL SYSTEM : Fail-safe

INFOID:0000000009019861

TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of

the main electronically controlled input/output parts is damaged.

If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system

is detected by TCM and the vehicle may be in a fail-safe mode. At this time, check the DTC code and perform

inspection and repair according to the malfunction diagnosis procedures.
